Trekking Down 'Endurance' - 1
The darker blue line in this approximate true-color mosaic from the panoramic camera on NASA's Mars Exploration Rover Opportunity shows the rover's position as of sol 170 (July 16, 2004). The rover is located at the end of the blue portion of the line, about 10 meters (32.8 feet) into "Endurance Crater." The rover took this image while sitting on the opposite edge of the crater.
The image also shows the "Karatepe" ingress, where the rover began its traverse down into "Endurance Crater" on sol 159 (July 5, 2004). One of the major goals motivating the rover team to carefully drive the rover further down into the crater is to follow up on clues observed so far involving the element chlorine and the mineral pyroxene. The rover has found that chlorine and pyroxene (a signature of basaltic, or volcanic, rocks) increase in concentration with deepening layers of rock. Scientists also hope to study the dunes, or "ripples," visible at the bottom right of this image. These dunes show strong signatures for basalt and could further develop the history of this area of Meridiani Planum.
